Subject: [ruby-core:86161] [Ruby trunk Bug#14611] Exotic method parameters	bug

Issue #14611 has been updated by Hanmac (Hans Mackowiak).


@phluid61 not so fast, ruby allows duplicate "_" as parameters so you can say that you don't want them and ruby should just ignore them
so you don't get a SyntaxError about duplicated argument name like your change did

----------------------------------------
Bug #14611: Exotic method parameters bug
https://bugs.ruby-lang.org/issues/14611#change-71040

* Author: bogdan (Bogdan Gusiev)
* Status: Open
* Priority: Normal
* Assignee: 
* Target version: 
* ruby -v: 2.4.2
* Backport: 2.3: UNKNOWN, 2.4: UNKNOWN, 2.5: UNKNOWN
----------------------------------------
Consider the following code:


~~~ ruby
def test(_, x, *_)
  x
end

test(1,2,3) # => nil
~~~

By some reason second parameter is nil when the rest of parameters declared as not used.
